Aqua-Kem can deodorize up to 40 gallons depending on time, temperature, and volume of accumulated waste. A one gallon bottle provides up to 16 treatments. Aqua-Kem is 100% biodegradable liquid and environmentally safe when disposed of properly. This is Thetford's highest strength, proven formula. Does not contains formaldehyde.

I have tried various products with mixed results. This product works well and consistently if used weekly. Even if we don't have the head pumped every weekend, I flush down a shot first thing and it eliminates any vent smell when flushing.
